Residuals from the itemss
« on: October 05, 2012, 05:24:44 AM »
Hi,

I've been trying to obtain a residuals table from the items (not from the cases or persons) and I've not found the command. I don't know what I'm missing... could you remember me what is the syntax for that?

Thanks!!

Luis

residuals are defined at the level of a combination of student and item.  ie the residual for item x and person n.  These are available from the show command.  For a summary of residuals by item you have the item fit statistics when you request  show items.
